Balanced Connections - Emotiva MPS-1 User Manual

Balanced Connections

If your preamplifier has balanced XLR outputs, it can be connected to the amplifier inputs as shown.
The amplifier will boost the preamplifier's output, up to a level suitable for driving speakers. The
overwhelming advantage of using the balanced XLR inputs is that there is superior noise rejection
over the common RCA type connections.
Make sure that the positive speaker wires do not touch the negative speaker wires, or any chassis
metal. This will cause a short circuit and may activate the protection circuitry. The 12 VDC trigger
connection shown can be used to turn the amplifier on when the preamplifier turns on. This is the
preferred method of activating the MPS-1. Alternatively, you could use the amplifier's SIGNAL switch
position. The amplifier will then automatically turn on when a preamp audio signal is received.
